Abstract
The invention relates to a fuel tank (1) for a motor vehicle comprising a venting line (2) which communicates with the atmosphere via at least one fuel vapour filter (5), comprising at least one filler pipe (6) and comprising at least one recirculation line (8) for recirculating fuel vapours during refuelling, via which the venting line (2) is connected to the filler pipe upstream of the fuel vapour filter (5) in the direction of flow, at least one reducing member (9) being provided in the recirculation line for altering the flow cross section depending on the refuelling volumetric flow. The fuel tank (1) according to the invention is characterized in that a valve body (10) which is freely movable in the recirculation line (8) is provided as the reducing member (9), and which is freely displaceable substantially without actuating elements between at least one first position with a reduced cross section of the recirculation line (8) and a second position with an enlarged cross section of the recirculation line (8).
